Play is the highest expression of human development in childhood for it alone is the free expression of what is in a child’s soul.
The mind grows by self revelation. In play the child ascertains what he can do, discovers his possibilities of will and thought by exerting his power spontaneously. In work he follows a task prescribed for him by another, and doesn’t reveal his own proclivities and inclinations; but another’s. In play he reveals his own original power.
